Benefits of adding a 10MHz Master Clock to a digital system


As a long time DCS stack owner (first Paganini, currently Vivaldi V2) I’ve been a convert to the value of dedicated clocking systems. In the context of a DCS setup this means including a dedicated clock unit that provides a combination of 44.1KHz and 48KHz signals to each of the other units in the system (the transport, DAC and up-sampler in the case of a full four box stack).

The DCS clocks are pretty darn expensive boxes and while they (like all DCS gear) benefit greatly from upgrading power cords, 75 ohm interconnects and feet I had never really thought that adding a further reference clock would bring any benefit. However piqued by the following recent review of the Vivaldi One in which the addition of both the Vivaldi clock and a Cybershaft 10MHz reference brought great benefit I wondered if I’d been mistaken and if an external 10MHz reference could add even more to my system.

Some on line research quickly made it clear that the Cybershaft OCXO clock used in the review is unobtanium so the question is who else makes a good clock? Online commentators seemed to think quite highly of the Ref10 from Mutec so that’s what I opted for from an Amazon seller. The Ref10 is a solidly made but very utilitarian box. It provides up to 8 outputs all on BNC, a mix of 6 at 75Ohm and 2 at 50Ohm so will match with whatever you have.

The DCS is 75Ohm so as soon as I had the Ref10 I installed it using a generic 75OHM BNC and the stock power cord. Notwithstanding recommendations to leave it on for 48 hours to stabilize the first impressions were very favorable. With the addition of the reference clock I was hearing further into the recording and also appreciating a surprisingly large increase in rhythmic consistency and bass realism (i.e. bass seemed crisper and less boomy with the elimination of a sense of overhang in the 80-120Hz range that had plagued my system before)

What then amazed me was how much further improvement upgrading the power cord (to Marigo Iridium V2) and BNC (to Marigo Apparition Extreme 75Ohm) brought - even more air and clarity. The final icing was optimizing the support under the Ref 10 with Marigo RHZ feet on a Marigo platform. I've now had the Ref10 in my system for several weeks and frankly it's probably the first time I'm really beginning to believe that digital can give my analog setup a real challenge -- with how I have it now I feel as if I'm hearing two increasingly similar takes on the same absolute -- digital converging on all the best in terms of space and realism I've found in analog, while the latter (with the recent addition of Ron Heydrich's latest power cord on my turntable PSU) getting the speed stability and rhythmic integrity that digital can do so well.

Overall in the context of a megabuck DCS setup it was surprising how much benefit a relatively modestly priced ($3595) professional grade add on brought. That I then added nearly $9K of tweaks to it probably speaks more to my obsessive nature (and budget I guess) but overall consider me a full convert to the benefits of 10MHz master clocking in any attempt to scale the heights of digital reproduction.

@folkfreak  - could not agree more. Have not heard the DCS clock but finally bought a 10MX clock. The improvement was startling. Without the clock there is a fog over inner detail. With the clock everything comes into focus. The higher you go in sampling rate, the bigger the difference the master clock makes.
Listen to Dletch....230 posts in 10 days. One of his 1st posts from 10 days ago states he got rid of all his CD's in the 1990's. YET he knows everything about Master Clocks and Jitter without ever having a CD Player past the 1990's. Don't you have anything more productive to do with your time then to post about topics that you have no knowledge/experience with?? Best wishes breaking the Audiogon Posts number....should take you less than a year at the rate your going. Hopefully its not all pointless nonsense like this one.
Look at riaa ....


Never designed any electronics. Does not know how a master clock interacts with electronics. Is told by the experts in making DACs\Players that a master clock not only is not beneficial, but is detrimental, but .....


Thinks he knows better. 


Like I said, you are free to waste your money, but you may want to learn how things actually work. It is an excellent inoculation against confirmation bias. 
Please go tell the above mentioned companies (MSB/Esoteric/DCS/Mutec/etc) that they dont know what they are doing.

Your right...I never designed electronics. Been retired since I was 44/45 and have worked with Hundreds and Hundreds of people in the Music Industry since 1987...Record Execs/Recording Engineers/Producers/Band Members/Concert Promoters and the like.Thats how I acquired..to date...more than 9000 Gold/Platinum Record awards featured on the Facebook page in my title. Yep....I have LOTS of money to blow. Whats your resume look like? Let me guess, based on your ridiculous number of posts you recently lost your job or recently retired and have nothing better to do with your time than make 30 posts a day. Look in the Yellow Pages for a Shrink and spare the rest of us from your endless tirades.
  10:30 A.M (EST) and you've already made close to 20 posts just today...Congrats!!
For the sake of y’all: commenting on things you have not heard on account of some spurious third party opinion is uncool and a waste of everybody’s time. Rspectful comments get you further than invective. And finally: enjoy the music, it’s the most beautiful hobby out there.

And for the avoidance of doubt: ‘mine is bigger’ even when demonstrably true isn’t going to make you a lot of friends or admirers.
